Definitions

  • the invention relates to a method for producing a plate-shaped soundproofing element for mounting below a ceiling, in particular below the ceiling of a large room or a hall.
  • a sound insulation element is known for example from DE-U-91 11 178.
  • the element has a core of compressed, bonded glass wool. After the production of this core layer, a glass fiber fleece is attached to each of the two flat sides, which is laminated on the outside with a layer of paint.
  • this soundproofing element has satisfactory acoustic properties, the insulation materials present in the core layer pose considerable health risks.
  • JP-A-2 006 653 it is known to produce sound-insulating layers using textile-like substances as the carrier layer, this carrier layer being provided with a coating made of a polyurethane prepolymer.
  • the carrier material can consist of cotton, wool, polypropylene, polyethylene, acrylic, acetate or similar materials.
  • the coated carrier layer is brought into a desired shape under pressure, this molding process is supported by heat or steam supplied from outside.
  • a suitable catalyst can be used to accelerate the reaction.
  • the layer described in JP-A-2 006 653 can serve both the purpose of sound insulation and sound insulation.
  • the layer according to JP-A-2 006 653 also poses problems in waste disposal. This is primarily due to the substances contained in the layer, which almost without exception require special disposal measures. This does not change the fact that cotton or wool can be used as the textile fabric, because this is provided with a coating of a polyurethane prepolymer in the course of the process, which in turn results in the above-mentioned problems in disposal.
  • the invention is therefore based on the object of developing a method for producing a plate-shaped soundproofing element which leads to a soundproofing element which can be disposed of without any problems in the course of waste disposal, the soundproofing element thus obtained with regard to its acoustic properties using the known soundproofing elements, for example on the basis of Rock wool, should be comparable.
  • sheep wool has a distinctly good acoustic insulation behavior which, according to initial estimates, is no worse than when using rock wool or glass wool.
  • sheep's wool is far superior to the two known materials, since it is a purely natural product which is subject to a natural decomposition process as waste.
  • the individual fibers are much longer than with rock wool and glass wool, so that there is no significant risk of the fibers getting stuck in the human lungs.
  • compressed sheep's wool does not have its own stiffness, which is why the invention proposes to bind the individual fibers of the sheep's wool in order to achieve an inherent stiffness in the core layer. This is done using a hardening binder. The binder is placed in the sheep wool compressed in a mold, the compression pressure being maintained until the binder binds the individual wool fibers. This creates an inherently stable plate, which is then provided with a porous lamination.
  • the inherent stability of the plate or core layer can be further increased by adding 10 to 25 percent, preferably about 20 percent, by volume to the sheep's wool.
  • sheep's wool cotton is a renewable natural substance.
  • the binder should also be made on a natural basis. According to one embodiment of the invention, it is therefore proposed that the binder consist of synthetic resin.
  • the lamination consist of an open-pore water-based paint layer.
  • an embodiment of the soundproofing element is characterized in that fastening elements are anchored in the core layer. This eliminates the need for additional measures to attach the fastening elements required for the arrangement of the sound insulation element below the ceiling to the outer surface of the sound insulation element.
  • Fig. 1 shows a sound insulation element 2 to be arranged below a ceiling in the form of a plate or baffle.
  • Fig. 2 shows that several rows of such soundproofing elements 2 are provided, each row in turn being composed of several soundproofing elements 2 arranged one behind the other.
  • the type of arrangement of the sound insulation elements 2 below a ceiling 1 can be chosen depending on the acoustic requirements.
  • the individual sound insulation elements 2 hang vertically downwards, while in the middle representation of FIG. 2 the sound insulation elements 2 are fastened horizontally under the ceiling 1 by means of rails 3.
  • the individual soundproofing elements 2 are suspended obliquely with the aid of guy wires 4.
  • the soundproofing element 2 has a core layer 5, which consists primarily of raw, compressed sheep's wool.
  • the individual fibers 6 of the sheep's wool are bound by a hardened binder.
  • Synthetic resin is used as the binder, which, in the hardened state, gives the core layer 5 such stability that it is inherently stable and the individual soundproofing elements 2 can therefore also be mounted firmly in a horizontal arrangement below a ceiling.
  • the raw, i.e. Unwoven sheep's wool placed in a rectangular shape and compressed therein.
  • Synthetic resin is then added, the compression pressure being maintained until the synthetic resin binds the individual wool fibers.
  • Such porous lamination is also possible at the edges if the hygienic requirements are met.
  • the lamination 7 also provides the soundproofing element 2 with sufficient resistance to infestation by mold and bacteria.
  • a fastening element 8 designed in the manner of a helical spring is embedded.
  • the supply element 8 can subsequently be screwed into the sound insulation element 2, but it can also be inserted during the manufacture of the sound insulation element 2 and then anchored in the core layer 5 during the hardening process.
  • the supply element 8 is provided at its upper end with a hook 9 which is suspended in an angular plate 11 slidably arranged on a T-rail 10.
  • the T-rail 10 is fastened either directly or at a distance below the ceiling and can also be embedded in it if sufficient space is left for inserting the plate elements 2.
  • synthetic resin is used as a binder for binding the individual fibers of the core layer.
  • Cellulose can also be used as a binder.
  • synthetic resin is preferred.
  • the inherent stability can be further increased by adding cotton to the sheep's wool in a volume fraction of approx. 20 percent.
